(54) DEVICE FOR INPUT OF INFORMATION 3 Information intended for input into the PCV is dialed on the keyboard I and through the encoder 2, which converts the decimal number to the binary-decimal code, entered into shift register 4. At the same time, the signals for pressing the information keys are received through the OR element 3 at the control block 6 and at the counter 5, the control block 6 generates shift pulses, by means of which information from the shift register 4 to the buffer register 7. The counter 5 counts the number of key presses . The command keys are pressed after a certain number of key presses. For example, the output DV pane of the digital on-board information center recorded in a memory cell must be dialed on the information keys and using the command keys to form a command to enter the number in the central computer and display information on the display unit 9 If the cell number is displayed With the actual numbers, it is necessary to double-click the information keys of the keyboard 1 and press once the corresponding command key. The command signals arrive at the keyboard 1 in block 8 of the comparison, where they are compared with the contents of the counter. 5. When the operator enters the information, two situations may arise: either the input was made correctly or not correctly. In the first case, the output from the comparison unit 8 sends a signal to the PCB to process the input information pn located in the buffer register 7. In the second case, from the output of the comparison unit 8, a signal is received to turn on the incipient block 9, reset the 4 shift register and block the information key and command keys of the keypad L, the signal from the output of block 8 will not be sent to the central computer, and block 9 of the display will show the operator the wrong sequence of input operations, In the keyboard 1, only the device setup key remains unlocked -keeping its original state, and for further work neobhodikyu pressing this key, in this case from I gyustupit keyboard reset command counter 5 in the initial state. Thus, the proposed device allows detecting an error of the input: operation, and until the end of the entire array of information, which leads to a reduction in the input time. Formula of the Invention A device for inputting information containing a keyboard whose command output is connected to the first input of the comparison unit, information outputs to the inputs of the encoder, the outputs of which are connected to the inputs of the shift register, the input of which is connected to the output of the comparison unit and the input block indication, and the output - with the buffer register, the control unit, the output of which is connected to the shift register, is distinguished by the fact that, in order to increase the reliability of the information input, the counter and the OR element, whose inputs are They are assigned to the keyboard outputs, and the output is to the control unit and the first input of the counter, the second input of which is connected to the command output of the keyboard, and the output to the second input of the comparison unit.
